CAR-TRUCK.

"SPECIFICATION forming part of Letters Patent No. 279,185, dated June12, 1883.

Application filed March 16,1883. (So model.)

To all whom it may concern:

Be it known that I, PATRICK REILLY,tt--Citizen of the United States,residing at Mattoon, in the county of Coles and State of Illinois, haveinvented a new and Improved Freight- Oar Truck, of which the following aspecification.

My invention relates to the combination of novel strengthening andsustaining plates, preferably of cast metal, with. the wrought-metalarch-bars of the side frames of freight or heavy burden car trucks,whereby the weakness of and difficulty experienced from. such trucksgiving out by the arch-bars springing out of place is avoided andovercome.

The object of my invention is to strengthen the truck at the pointswhere practical tests have demonstrated it is most liable to break. Thetests made with respect to this class of car-trucks have proved thatthey all give out by the arch-bars springing out of place; and toprevent such springing of these bars, when under great strain andpressure, I have contrived the invention of providing properlyshaped andstrong yet light metal plates, pret erably of cast metal and skeleton inform, and bolting these plates between the arch-bars, as

avill be more fully understood from the accompanying drawings, in which-Figure 1 represents a view truck partly in elevation and partly invertical section, and Fig. 2 a vertical crosssection of one of the sideframes in the line r :1: of Fig. 1..

The side of truck-frame A, as represented, is of ordinary construction,being the style almost universally used. \Vithin the spaces formed bythe converging and united archbars a a of the side frame I app] meta-lplates B of a form. corresponding in outlineto the spaces in which theyare fitted, as shown. These plates in cross-section in any direction areof angle-iron, form, in order that they shall have the necessarystrength and yet not be too heavy, as shown at I), Fig. 2. The width ofthe bearing afforded by the plates is equal to In the drawlar in formand as abutting into the corner formed at the meeting points of thearch-bars of my improved a. a. The plates B are also shown as terminating at their vertical. edges on one side of the vertical supportingcolumns and bolts, as at C O of the truckrframe, and they are shown asmade of cast metal and skeleton-that is, with an opening, (Z, throughtheir panel portion. The plates need not be cast metal, nor exactlytriangular in form; but the metal and form mentioned willbe i'oundpreferable to any others. \l'hw'mght metal and various other suitableshapes, either skeleton or solid, might be used with great advantage ascompared with trucks not supported by plates of any kind. The plates arefirmly secured to the arch-bars a c by'either bolts or nuts ff, or byrivets, or by other suitable strong fastenings, and when in position thearch-bars will be held by them from springing out of place, being firmlybraced, stiffened, or stayed and supported against strains and pressure.

The truck-columns might have the supports for the arch ed bars formed onthem; or flat bariron for supports might be bent into either triangular, V, or A form, or bars forming beveled knees or bearing-surfacesfor the arched bars might be adopted as an equivalent. The latterconstruction-viz., supports forming beveled kneeswould be the same asthough the supports shown were cut in two at y 3 Fig. 1, and the portionon the right side of y 3 were dispensed with.

The truck herein described made of wroughtiron arch-bars, which areunited at their ends upon the guides or supports for the journal-boxes.They'are also kept apart by vertical columns and bolts, which latterpass through the bottom wrought-iron straps. This descri ition. of truckis almost universally adopted, with here and there slight modificationsin its form and. construction, and it is to thischaracter of wrought-1netal truck that my invention is to be applied, as hereinbet'oredescribed and shown.

11 am aware that wrought-metal straps are well known as strengtheningmeans applied to beams of steamboat-engines and many other structures;but I am not awareth at web-pl ates, which form hearings on either sideof the vertical columns of a truck-frame constructed of upper and l owerwrought -metal arch-bars, have ever been employed for the purpose and inthe manner I have showni. 6., for preventing the arch-bars springing upbetween the vertical column-supports and the bearings for theaxle-journalsa difliculty which has been experienced with a greatVariety of the wroughtmetal truck-frames by special'tests.

I also am aware that a cantruck frame made 'plates, which form a bearingfor the arched bars, is common, and I make no claim to the sameseparately considered; but

\Vhat I do claim as my invention, and desire to secure by LettersPatent, is

1. A wrought-metal side frame, A, fora cartruck, provided with confinedwroughtmetal arched bars, with sustainingplates B applied and confinedbetween them, forward of and also in the rear of the middle cross beamor beams and between the converged portions a a. of the frame A,substantially as and for the purpose described.

2. Awroughtmetal truck frame, A, consist abutments for the bars areafforded in front of and also rear of the middle cross beam or beams ofacal-truck, substantially as described.

3. The combination, withthe'wroughtmetal side frame, A, of angularplates B, applied between and secured in position against the bars a a,substantially as and for the purpose described.

4. The combination, with the wrought-metal arched bars of thetruck-frame A, of skeleton angular plates B, said plates being appliedbe tween and secured in position against the bars, substantially as andfor the purpose described.

5. The combination, with the wrought-metal arched bars ca, having metalplates B, said plates being applied between and secured in positionagainst the converged ends of the arched bars, substantially as and forthe purpose described.

6. The wrought-metal truck-frame A, provided with a plate, B, on eachside of its vertic-a1 columns and bolts (7, and between its slopingsides, of thearched bars a a, substantially as and for the purposedescribed.
